Cape Coast was founded by the people of Oguaa and the region ruled over by the paramount chief, or Omanhene, is known today as Oguaa Traditional Area. Cape Coast is one of the most historical cities in Ghana. Portuguese colonists built a trading fort in the area. In 1650, the Swedes built a lodge that would later become the better known Cape Coast Castle, which is now a World Heritage Site. Most of the modern town expanded around it.
